Abstract
A connector design for connecting rotor coil end turns and an exciter/rectifier assembly to a rotor bore copper conductor in a dynamoelectric machine. The design includes a terminal stud or pin sized to be closely received in a telescoping manner in a cylindrical receptacle which is fixedly attached to the rotor windings. A similar cylindrical receptacle extends from the other end of the rotor toward the exciter/rectifier assembly. The stud or pin in each case is also modified to include grooves for accepting resilient, sliding electrical contacts so that a resilient electrical contact is obtained when the stud is positioned within the receptacle. The connector elements are also sufficiently rigid as to withstand shock, centrifugal forces at operational speeds, and rotation direction reversal, but which also allows sufficient radial and axial movement to accommodate coil movement associated with rotor temperature and speed changes while simultaneously maintaining a low resistance current path.
